The treatment effects of non -operation and operation on different types of injuries were observed and com pared. Results Follow-up time ranged from two months to tw o years. There were three cases with testicular atrophy, one with chronic pain l asting for one year and eight with non-operation. All of 22 cases treated with surgical operation were good except for one with sperm disorder due to bilateral testicular trauma. Conclusions Testicular trauma is a speci al type of trauma. Ultrasound is an important diagnostic method for testicular trauma. Surgical exploration should be performed as soon as possible so as to a void testicular atrophy and sperm disorder.

Objective To explore the relationship between the expression of matrix metalloproteinase (MMP) and tissue inhibitor of metalloproteinase (TIMP) in gestational trophoblastie diseases and its invasiveness.Methods The expression and distribution of MMP-7,MMP-9,TIMP-1 and TIMP-2 were determined by immunohistochemistry PV-6000 in 49 cases of hydatidiform mole (eight of them with malignant transformation),six cases of invasive hydatidiform mole,two cases of choriocarcinoma and 18 cases with normal villi in early pregnancy.Results The expression of MMP-7,MMP-9,TIMP-2 and MMP- 9/TIMP-1 was significantly higher in choriocareinoma,invasive mole and malignant transformed mole than that in normal villi in early pregnancy and non-malignant transformed mole (F=10.950,7.760,7.304, 3.442;P

Objective: To observe the effects of acupoint thread-embedding therapy on serum apelin and glucagon-like peptide-1 (GLP-1) in type 2 diabetes mellitus patients with obesity due to dampness-heat encumbering spleen.Methods: Sixty-six patients were randomly divided into a control group and an observation group according to the random number table method, with 33 cases in each group. Patients in the control group were treated with exenatide and metformin, while patients in the observation group were treated with additional acupoint thread-embedding. After 12-week treatment, the obesity-related indicators, including body mass index (BMI), waist circumference and body fat rate, the glycometabolism indicators, including fasting blood glucose, 2 h postprandial blood glucose and glycosylated hemoglobin, and the lipid metabolism indicators, including total cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C), as well as serum apelin and GLP-1 levels were observed in patients of the two groups. Results: After treatment, the BMI, waist circumference and body fat rate of patients in the two groups were all reduced (all P<0.05), and were lower in the observation group than in the control group (all P<0.05); the fasting blood glucose, 2 h postprandial blood glucose and glycosylated hemoglobin levels of patients in both groups were all decreased (all P<0.05), and were significantly lower in the observation group than in the control group (all P<0.05); the TC level was decreased (P<0.05), while the TG and LDL-C levels did not change significantly in the control group (both P>0.05); the TC, TG and LDL-C levels were all significantly reduced in the observation group (all P<0.05), lower than those in the control group (all P<0.05); the serum apelin level was decreased (P<0.05) and the serum GLP-1 level was increased (P<0.05) in the observation group, statistically different from those in the control group (both P<0.05). Conclusion: Combined with the conventional medication, acupoint thread-embedding therapy can significantly improve the obesity-related indicators, glycometabolism and lipid metabolism in type 2 diabetes mellitus patients with obesity due to dampness-heat encumbering spleen. This may be achieved by regulating the serum apelin and GLP-1 levels.

Background The surgery for congenital idiopathic nystagmus has make great progression recent year,but the influence of surgery on visual function is closely concerned.Objective This work was to study the surgeries for congenital idiopathic nystagmus with or without strabismus and explore the effect of horizontal rectus muscle surgery on the visual function and ocular movement in congenital idiopathic nystagmus.Methods This was a case-observational study.Sixty cases with idiopathic congenital nystagmus were enrolled assigned to four groups as follows:The patients of group Ⅰ appeared the head postures of less than 15 ° and heterotropia less than 15△underwent extraocular proprioceptiou resection,and those of group Ⅱ presented with the head postures of less than 20° and heterotropia more than 15△ underwent extraocular proprioception resection and stabismus surgery.In the group Ⅲ,the patients had the head postures of more than 15° and heterotropia less than 15△ underwent Park's surgery and part of them underwent extraocular proprioception resection) and the cases in group Ⅳ were selected with the head postures of more than15° and heterotropia more than 15△ underwent Park' s surgery and strabismus surgery ( part of them underwent extraocular proprioception resection).Baseline and follow-up evaluations included the best distance and near corrected visual acuity,head posture,ocular movement and Titmus stereotest.The examination results were compared between before and after operation.Results One year after operation,monocular and binocular distance visual acuity improved significantly in all four groups ( monocular:t =6.00,8.94,11.76,16.41,P =0.00 ; binocular:t=4.81,P=0.01 ; t =6.27,4.25,4.18,P =0.00 ),but monocular and binocular near visual acuity improved significantly only in groups Ⅲ and Ⅳ after operation compared with before operation ( monocular:t=2.91,P=0.01 ; t =5.32,P =0.00 ; binocular:t =3.36,t =4.30,P =0.00 ).The compensatory head posture from 39 subjects was disappeared after operation,showing an evident difference between before and after surgery ( group Ⅲ:t =29.90,P=0.00;group Ⅳ:t=16.91,P=0.00).Strabismus were corrected rightly for 24 patients and undercorrection for 2 patients.( group Ⅱ:t =29.15,P =0.00 ; group Ⅳ:t =36.79,P =0.00 ).The binocular visual function of 23 cases with the age below 12 years were improved throughout the follow up duration ( t =12.06,P =0.00).Conclusions Park' s surgery,extraocular proprioception resection and strabismus corrective operation can improve the visual function and head posture in congenital idiopathic nystagmus patients.

Background Congenital nystagmus is a common disease threatening visual function.The clinical description of congenital nystagmus is still not enough now. Objective The aim of this study was to report the motor and sensory characteristics of congenital nystagmus. Methods A retrospective clinical case analysis was designed.The clinical data of 376 patients with congenital nystagmus were collected.These patients were diagnosed in Henan Eye Institute from January,2005 to August,2011.The clinical characteristics of patients,including age,pedigree analysis,nystagmus classification,ocular alignment,visual acuity,refractive error,stereoacuity and oscillopia,was summarized.Informed consent from all patients and custodian were obtained. Results The age distribution of most patients was ＞5-10 years and ＞ 15-20 years,with the percentage 24.73％ and 24.20％,respectively.Of 376 patients,sensory defect nystagmus was 172 cases,and that of motor sensory defect was 204 cases.The most common inheritance pattern was autosomal dominant.Conjugate uniplanar horizontal oscillations were found in 73.94％patients,and strabismus was found in 66.36％ in this study.Sensory defected subjects did not show a statistically significantly higher strabismus incidence when compared with the idiopaths (x2 =3.048,P =0.081 ).The binocular distance vision in all the subjects was declined in comparison with normal eyes,the best corrected vision was 0.27 ±0.11 and 0.50± 0.13 in sensory defected nystagmus and idiopaths nystagmus respectively,showing a significant difference( t =16.495,P =0.000 ).The incidence of refractive error in this study was 77.62％.Incidence of astigmatism(75.17％ ) was higher than that of myopia and hyperopia ( 39.03％ and 36.12％ ).No significant difference was seen in refractive error incidence between the sensory defected and the idiopaths (x2 =1.337,P =0.248).Patients of 65.18％ displayed non-stereoacuity or very gross acuity levels (3000) in this study,and the patients with idiopathic nystagmus showed better stereoacuity level in comparison with sensory defected ones (x2 =7.058,P =0.008 ).Five of 313 patients existed experienced oscilopla under binocular viewing conditions.Conclusions Autosomal dominant inheritance is the most common pattern of congenital nystagmus.Conjugate uniplanar horizontal oscillation is thought to be a common type of nystagmus.Incidence of strabismus is higher,and visual acuity and stereoaeuity are worse in congenital nystagmus than in common population.Oscillopia is seldom found in congenital nystagmus.

Objective:To evaluate the outcome and prognostic factors of conventional radiotherapy followed by intensity-modulated radiation therapy (IMRT) as a boost combined with chemotherapy in the treatment of high-grade gliomas (HGG). Methods:From Nov. 2004 to Nov. 2006, 112 HGG patients were treated with conventional radiotherapy followed by IMRT as a boost combined with chemotherapy. The radiotherapy regimen included first-course conventional radiotherapy and latE-course IMRT as a boost with the total radiation dosage of 57.5- 62.5Gy (27-29 fractions in 37-45 days). All the patients received chemotherapy. Sixty-three patients received temozolomidE-based chemotherapy and 49 patients received semustine plus teniposide chemotherapy. The treatment reaction was recorded. The overall survival rate and local progression-free survival rate were calculated. The prognostic factors were analyzed by using multivariate COX regression model. Results:The acute treatment toxicity was the most at grade 1 to grade 2 and no grade 4 adverse reaction was observed. Three cases had late radiation-induced brain necrosis. The overall 1-, 2-, and 3-year survival rates were 78.9%, 54.7%, and 30.8%, respectively. Multivariate analysis revealed that tumor location (P=0.001) and KPS score (P=0.011) were independent prognostic factors. The 1-, 2-, 3-year local progression-free survival rates were 63.8%, 38.9%, and 10.5%, respectively. Multivariate analysis revealed that tumor location (P=0.001), KPS score (P=0.001), and histologic type (P=0.005) were independent prognostic factors. Multivariate analysis did not reveal the significant correlation of temozolomide chemotherapy with the prognosis of the patients. Conclusion:Postoperative conventional radiotherapy followed by IMRT as a boost combined with chemotherapy has better short-term efficacy in the treatment of HGG and the adverse reaction is tolerable. KPS score, tumor location, and histologic type are important prognostic factors. Temozolomide chemotherapy is not associated with the prognosis of patients.

Objective To investigate the effects of high flow hemodialysis (HFHD) on cardiac function in uremia patients. Methods A prospective randomized controlled study was conducted. Sixty patients who were diagnosed with uremia, taken maintenance hemodialysis (MHD) and 30 healthy controls admitted to the Second People's Hospital of Guiyang from December 2014 to June 2015 were enrolled. They were randomly divided into two groups:HFHD group (HFHD three times a week) and the routine hemodialysis group (HD group, HD three times a week), with 30 in each group. Patients in each group were received hemoperfusion and hemofiltration once a month. Before the treatment and 6 months after the treatment, venous blood from all the patients were collected for testing the brain natriuretic peptide (BNP), cardiac troponin T (cTnT) and the ultrasound cardiograph were done at the same period by a special person, the left ventricular end diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), the left ventricular end diastolic volume (LVEDV), left ventricular end systolic volume (LVESV), left ventricular posterior wall thickness (LVPWT), interventricular septum thickness (IVST), early and late diastolic blood flow to the largest ratio (E/A), left ventricular ejection fraction (LVEF), left ventricular mass index (LVMI) were recorded. Results Compared with the health control group, BNP, cTnT, LVEDD, LVESD, LVESV, LVPWT, IVST were significantly increased, LVEDV were significantly lowered before treatment in the HD group and HFHD group. But no significant differences in the above indexes and E/A, LVEF, LVMI between two groups were found. Compared with the data before treatment, the BNP, LVPWT were significantly lowered after treatment in HD group [BNP (ng/L): 641.50±60.09 vs. 2676.20±454.30, LVPWT (mm): 10.57±1.16 vs. 12.57±1.41, both P < 0.05]. The BNP, LVPWT were significantly lowered in HFHD group as compared with HD group [BNP (ng/L): 253.10±48.77 vs. 641.50±60.09, LVPWT (mm): 9.29±1.08 vs. 10.57±1.16, both P < 0.05]; in addition, the cTnT, IVST, LVMI were significantly lowered after the treatment in HFHD group compared with those before treatment [cTnT (μg/L): 0.014±0.005 vs. 0.028±0.011, IVST (mm): 7.81±1.69 vs. 11.04±2.23, LVMI (g/m2): 149.10±15.77 vs. 158.70±17.25, all P < 0.05], and the LVEF were significantly increased in HFHD group as compared with those before treatment (0.574±0.068 vs. 0.528±0.082, P < 0.05). Conclusion HFHD has obvious advantages than the routine HD in improving cardiac function of uremia patients.

Objective To observe whether hepatitis B vaccine enhance the treating effect of cyto-kine induced kill(CIK) cells on hepatitis B virus transgenic(HBV-Tg) mice. Methods The HBV-Tg mice were treated with CIK cells by peritoneal injection and hepatitis B vaccine by hypodermic injection. The HBV DNA level were tested by real-time PCR,T lymphocyte subgroup were detected by flow cytometry and the pathological diversify of hepatic tissue were observed by HE staining. Results The HBV DNA loading in peripheral blood of HBV-Tg mice decreased after CIK cells were treated and CD3~+ , CD4~+ and CD8~+ cells increased which were enhanced after CIK cells combined with hepatitis B vaccine. Conclusion Hepa-titis B vaccine enhanced the treating effect of CIK on HBV-Tg mice which may be implemented by increased the blood level of CD3~+, CD4~+ and CD8~+ cells, especially CD8~+ cells level.

ObjectiveTo investigate the factors related with curative effect and prognosis of postoperative radiotherapy for nasal and paranasal sinuses carcinoma.MethodsThe data of 95 patients with nasal and paranasal sinuses carcinoma and received postoperative radiotherapy were reviewed retrospectively. Kaplan-Meier method was used to analyze the survival, Logrank test used to compare the differences between different groups. Multivariate analysis was performed by Cox proportional hazard model.ResultsThe overall 1, 3, 5, 10-year survival rates of 95 patients were 84.2%, 50.5%, 44.2% and 20% respectively. Univariate analysis showed that sex, age, operative modality and tumor dose were not related with survival. Histological and clinical stages were related with survival. Multivariate analysis indicated that histological and clinical stages were independent prognostic factors. The follow-up results showed that visual disturbance, xerostomia, dysaudia were the major side effects.ConclusionPostoperative radiotherapy can improve therapeutic effect in the treatment of nasal and paranasal sinuses carcinoma, and histological and clinical stages are the independent prognostic factors effecting prognosis.

OBJECTIVETo investigate the effects of antibiotic-PMMA (polymethyl-methacrylate) beads combined with external fixator in treatment of infected fracture nonunion.

METHODSTwenty-two cases of infected fracture-nonunions were reviewed involving 20 male and 2 female with an average age of 34.68 years (ranging 21 to 74 years). The data consisted of 9 cases of tibial fractures, 2 distal fractures of the femur, 6 femoral shaft fractures, 3 intertrochanteric fracture of the femur and 2 humeral shaft fractures. The procedure included thorough debridement to wipe out dead bone and granulation tissue, then antibiotic-PMMA bead chains imbedded into the dead space. One week later, secondary debridement was performed, antibiotic-PMMA bead chains were changed according to result of bacterial culture and susceptibility test, and fractures were stabilized with external fixator. Three months after debridement, antibiotic-PMMA bead chains were taken out and bone graft with autogenous iliac cancellous bone chips was performed.

RESULTSThe mean follow-up period was 19.98 months (ranging 15 to 28 months). Infection was controlled in 20 cases. One tibial fracture and 1 intertrochanteric fracture of the femur needed repeated debridement 2 and 3 months after bone grafting respectively,because of infection recurrence and sinus formation. All 22 cases achieved bony union averaged 15.09 weeks after bone grafting with a range of 8 to 24 weeks.

CONCLUSIONThorough debridement, imbedding antibiotic-PMMA bead chains combined with external fixator and staged bone grafting has proven to be effective and simple for treatment of infected fracture nonunion. The antibiotic bead delivers high tissue levels,obliterates dead space, aids bone repair.
